This contribution illustrates the efforts currently conducted in the SPIDER project, a third-party funded
project focussing on an unconventional way of thermal building retrofit. SPIDER thereby stands for
Subtraction as a measure to Preserve and Insulate historic Developments by Electric Robots. As an
exploratory project, the principle feasibility of using façade-climbing, autonomous robots, which
perform drill work in existing facades to integrate insulating (air) pockets, is examined. In contrast to
conventional thermal retrofit of facades, the present approach yet has to be thoroughly explored. The
idea is in detail meant for richly decorated facades of high architectural meaningfulness, which cannot
be subjected to conventional thermal insulation. Thereby, a number of challenges have to be addressed:
First, the utilization of autonomous robots as building retrofitting machines sounds tempting, but is
connected with a large number of technological and organizational obstacles that need be overcome.
Moreover, the use of a subtractive approach encompasses several constraints connected to structural
stability and building physics. This contribution highlights the different research questions and
challenges as well as provides a first overview about the findings of the research project.
